Definitions

  • the invention relates to a premix gas pilot burner with an air inlet arranged downstream of the gas inlet and a mixture outlet opening, which is opposed by a flame sensor electrode.
  • Gas pilot burners are known in numerous embodiments, e.g. from DE-GM 1 870 006, 1 897 906, 69 39 679, 69 47 963, 70 37 072, 72 18 018 and 74 01 561.
  • Gas premix burners according to the preamble of claim 1 are known from DE-GM 70 37 072 and DE-AS 10 09 126.
  • the wire mesh has a constant mesh width over its entire extent.
  • DE-AS 10 09 126 the apex area of the wire mesh opposite the outlet opening of the gas pipe is covered by a disk.
  • a gas burner for gases with low ignition speed in which the burner plate placed on the burner head is made of a gas-permeable material and in such a thickness that gas passes through the central gas passage opening for the main flame under substantially reduced pressure the burner plate can pass through. It forms a ring of small holding flames surrounding the main flame.
  • a similar construction shows DE-GM 69 39 679, where a
  • Flow channel for the main outlet opening of the gas is arranged behind the inlet nozzle of the gas in the mixing space so that this flow channel is mainly fed with pure fuel gas.
  • the burner plate surrounding this main flow channel is provided with a large number of small gas passage openings surrounding the main outlet opening, which give rise to a ring of small ionization flames in which the sensor electrode of an ionization flame detector is immersed.
  • a premix gas pilot burner is to be created which is inexpensive to manufacture and which can produce a stable flame even with fluctuating gas pressure.
  • a dome-shaped or paraboloid-shaped wire mesh can be produced in a simple manner by deforming a flat wire mesh with a constant mesh size over a mandrel. It can be fastened in a sleeve that can be screwed or plugged onto the burner mouth.
  • Such a production of the wire mesh also has the advantage that the mesh size of the mesh is larger in the apex area of the curvature than in the edge areas of the curved wire mesh.
  • the grid creates a larger ground area for a flame sensor that works on the flame ionization principle and thus a stronger flame flow.
  • the counter electrode faces the mixture outlet opening and can optionally also be used as an ignition electrode.
  • a separate ignition electrode is directed laterally onto the curved wire mesh.
  • Figure 1 is a side view of a pilot burner assembly with flame electrode and separate ignition electrode.
  • Fig. 2A in an enlarged scale a section through the curved wire mesh
  • Fig. 2B on the same scale an end view of the wire mesh.
  • Has paraboloids It is made from a flat wire mesh with a constant mesh size by deforming it into a dome-shaped shape over a correspondingly shaped mandrel. At the same time, the mesh size in the apex region 10 of the grille is larger than in the edge region 11 thereof.
  • the wire grate deformed in this way is held by a sleeve 8 which is screwed onto the outlet opening of the burner tube 2 or is attached by a snap connection.
  • the flame sensor electrode 3 can also serve as an ignition electrode for forming the ignition sparks when the burner is started.
  • the ground area enlarged by the grid 9 leads to an increased ionization current between the burner 2 and the sensor electrode 3, as a result of which the operation of the flame sensor is improved.
  • the new pilot burner is characterized by low manufacturing costs because the additional lateral outlet openings, which are often required in known pilot burners, are eliminated and it is composed of automatically produced turned parts and can also be assembled automatically.

Abstract

L'invention concerne un brûleur à prémélange à gaz, dans lequel l'orifice de sortie du mélange (8) est recouvert d'un treillis (9) à bombement cupuliforme qui forme une surface massique agrandie pour un détecteur de flamme fondé sur le principe de l'ionisation de flamme, et produit une couronne de petites flammes de retenue qui stabilisent la flamme principale.
